Description
Verfahren zur Herstellung von Gegenständen, bei denen es auf hohe Verschleissfestigkeit ankommt, insbesondere Radreifen. Es ist bereits vorgeschlagen worden, zur Herstellung von Gegenständen, bei denen es auf gute Verschleissfestigkeit ankommt, Stähle zu verwenden, welche eutektoitl sind und dabei b1angan als Doppelkarbidbildner in einer solchen Menge enthalten, dass der Kohlenstoffgehalt bei rein perlitischem Ge füge unterhalb von 0,9,7o liegt, so :dass der Mangangehalt etwa 0,6 bis<B>0,8%</B> beträgt.
Das Mangan kann ganz oder teilweise durch andere Doppelkarbidbildner, wie Chrom, Molybdän, Wolfram oder Vana.din ersetzt werden. Die Verschleissfestigkeit des Stahles lässt sich weiterhin steigern, wenn der Sili- ziumgehalt über die normalerweise in mit Silizium beruhigten Stählen vorhandene Menge hinausgeht, also, beispielsweise 0,35 bis 0,80% beträgt.
Es wurde gefunden, dass die Eigenschaf ten :der verschleissfesten Gegenstände aus einem eutektoiden Stahl mit rein lamellar- perlitischem Gefüge, der Doppelkarbidbild- ner in einer solchen Menge enthält, dass :der Kohlenstoffgehalt unterhalb von<B>0,9%</B> liegt, durch einen Nickelzusatz in überraschendem Masse günstig beeinflusst werden. Bei er höhtem Verschleisswiderstand steigt gleich zeitig die Streckgrenze und nehmen Dehnung und Zähigkeit zu.
Der Höchstwert der Nickelgehalte der verschleissfesten .eutek- toiden Stähle ist so zu wählen, :dass die Grenze zwischen dem perlitischen und mar- tensitischen Gefüge nicht überschritten wird. Für :die hier in Frage kommenden Kohlen- stoffgehalte liegt dieser Höchstgehalt des Niekels zwischen 6 und 7 %.
Bei :der Her stellung der mit Nickel legierten eutektoiden Stähle ist zu berücksichtigen, :dass Nickel zum Teil in die Zementitlamellen :des Perlits eingeht und infolgedessen der Kohlenstoff gehalt etwas herabgesetzt werden muss.
Die untere Grenze des wirksamen Nickel gehaltes liegt bei etwa. 0,5 %. Eine weitere Verbesserung kann .durch einen gleichzeiti- gen Kupferzusatz in Mengen von 0,2 bis 1,57o erzielt werden.
Beieinem Stahl der genannten Art kann als Doppelkarbidbildner z. B. Mangan in Mengen von etwa 0,6 bis 0,8% verwendet werden. Das Mangan kann ganz oder teil weise durch andere Doppelkarbidbildner, wie Chrom, Molybdän oder Vanadin ersetzt wer den. Es empfiehlt sich ferner, von einem er höhten Siliziumgehalt von beispielsweise 0,35 bis 0,80% Gebrauch zu machen.
Process for the production of objects where high wear resistance is important, especially wheel tires. It has already been proposed to use steels which are eutectic and contain b1angan as double carbide formers in such an amount that the carbon content with a purely pearlitic structure is below 0.9 for the production of objects for which good wear resistance is important .7o is so: that the manganese content is about 0.6 to 0.8%.
The manganese can be completely or partially replaced by other double carbide formers such as chromium, molybdenum, tungsten or Vana.din. The wear resistance of the steel can be further increased if the silicon content exceeds the amount normally present in steels killed with silicon, that is, for example 0.35 to 0.80%.
It was found that the properties: of the wear-resistant objects made of a eutectoid steel with a purely lamellar-pearlitic structure, the double carbide formers in such an amount that: the carbon content below <B> 0.9% </B> can be influenced favorably to a surprising degree by an addition of nickel. With heightened wear resistance, the yield point rises and elongation and toughness increase.
The maximum value of the nickel content of the wear-resistant, eutectoid steels is to be selected so that: the limit between the pearlitic and martensitic structure is not exceeded. For: the carbon content in question here, this maximum content of the Niekel is between 6 and 7%.
In: the manufacture of eutectoid steels alloyed with nickel, the following must be taken into account: that nickel is partly incorporated into the cementite lamellae: of the pearlite and, as a result, the carbon content has to be reduced somewhat.
The lower limit of the effective nickel content is around. 0.5%. A further improvement can be achieved by adding copper at the same time in quantities of 0.2 to 1.57o.
When a steel of the type mentioned can be used as a double carbide z. B. Manganese can be used in amounts of about 0.6 to 0.8%. The manganese can be wholly or partially replaced by other double carbide formers such as chromium, molybdenum or vanadium. It is also advisable to make use of an increased silicon content of, for example, 0.35 to 0.80%.
